Nube to LibreCAD - Dimension setting problems

I am confused but I think that this serves as both introduction and explanation of my issues.

Introduction:
I am a retired Electric Power EE and designing and managing energy for non-profits.  I have had experience using Visio for technical drawing many years ago need a 2D CAD tool in my present work.  


My experience is 24 years in an electric utility, 7 in fiber telcom, and 12 in heavy equipment embeaded systems and off grid renewables for telcom towers.

Issues:
I need technical floor plans with dimemsions to define insulation placement, wiring upgrades, and new energy efficient equipment.

LibreCAD v2.2.1.2 delivers the platform but having problems with dimansioning.  Specifically:
I use "Alined" dimension option on a line in a new layer, and it overlays the dimension lines and arrows directly on my element.  The dimension are correct but hides the element.

Questions:
1. My Dimension Lines, arrow, and ticks do not have an offset like the extension lines - where is this adjustment.
2. Cannot find the blue dots for dragging.
3. I am using a different layer than "0".  I think I read that layer 0 shoud be empty.  I read that somewhere I think.

Please advise
Jim

well, improving support of dimensioning is now in progress, and I suppose in nearest 2-3 weeks there will be release where it will be extended.

As for your questions:
1) please check Drawing Preferences -> Dimensions tab, there are setting that controls dimensions rendering.

2) mmm... that's strange. For linear dimensions, there should be 4 points - 2 definitions points (where extension line starts), definition point and text mid point. Please select dimension object and check again.
In 2.2.2 alpha branch, it is possible to increase the size of the grip point via settings (https://github.com/LibreCAD/LibreCAD/releases/tag/2.2.2_alpha-latest).

3) actually, as for 0 layer - at least in LibreCAD, there are no technical limitations that prevents you to keep your objects in that layer (yet you can't delete layer 0).
If you create blocks - it's better to keep objects for the block within layer 0.

for 1.)

there is no fixed offset for dimension lines towards the dimensioned object.
You position it manually by mouse dragging when creating it. You have to enable  "Free Snap" otherwise it will snap to the extension lines origin and thus lying on the object.

Good Catch: It was that SNAP that foiled my dimensioning.

Thanks
Jim

Thanks

I am more knowledgeable about and that has solved my dimensional issue.

> It was that SNAP that foiled my dimensioning.

In 2.2.2 snapping for dimensions is relaxed. There dim lines may be snapped precisely to adjacent dimensions if SHIFT is pressed, so the current snap mode is ignored while SHIFT key is hold.
